Title: Diagram of a Chute Dropping Water to a Turbine
Date: no date
Source: Descriptive Catalogue
Description: This cross-section diagram of part of the Pillsbury "A" Mill shows how water was transported to the turbines that were used to run the machinery in the mill.
- The turbine is located at the bottom of the water-filled pit or flume. Knowing what you do about waterwheels and turbines, what is the purpose of the flume?
- The description along the side of the diagram says that the unit has a 50 foot "head," meaning a drop of 50 feet. Is there any benefit in making the water go so far to reach the turbine?
- Can you tell from the source about how big this turbine is?
- Beside the words that tell you this flume was at a mill in Minneapolis (across from St. Anthony), what else might be a clue to where this mill was located?
